Title: Digital data remultiplex device which efficienlty allocates band
Inventor: DATE SATORU
IPC: H04N7/16
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To suppress the deterioration of quality to a minimum, to reduce device cost and to efficiently allocate a band by obtaining the combination of programs multiplexed with a prescribed output transmission line, obtaining an excess band in the output transmission line at multiplexing with the combination and selecting combination whose excess band becomes minimum among the obtained excess bands. SOLUTION: A combination of multiplexed programs is obtained for an i-th output transmission line in a combining operation process 21. Then, an excess band multiplexed with the i-th output transmission line is obtained for obtained combination in an excess band operation process 22. When the excess bands on all the transmission lines (i) are obtained, the combination of the least excess band is set to be optimum combination, and thus is obtained in an optimal combination decision process 23. Thus, the excess band is reduced by efficiently allocating the band to the transmission band of an output side. Then, by converting the transmission bit rate of the selected program, efficient transmission can be realized.

Title: Gear transmission type rotary actuator
Inventor: TERENSU JIYON KEIPUUERU
IPC: F16H19/00
Filed: 1989-01-31
Abstract: PURPOSE: To balance torque load between gear trains by providing means for allowing limited rotating motion between adjacent gear trains of sun gears. CONSTITUTION: When a plate 52 is rotated with respect to a plate 55 in one direction, a lever element 57 is rotationally moved to cause a plate 49 to relatively rotated in the opposite direction. In this case, the element 57 is rotationally moved around the center plane of the plate 55. The plates 49, 52, 55 and the element 57 are thus operated as a differential mechanism 37 for connecting an input shaft 20 to sun gears 40, 53. Even when torque load on a ring gear 23 is increased, all torque of an actuator is not operated on this gear. When relatively low torque load on the gear 22 is, in turn, increased by the deflection of a sub-vane, the sun gear 53 is driven. The lever 57 is rotationally moved around a spherical portion 58 with relative rotation between the sun gears 40, 53 until torque on the ring gears 23, 22 is balanced.

Title: Direct electric heating method for metallic sheet
Inventor: HAMADA KOICHI
IPC: C21D1/40
Filed: 1996-02-06
Abstract: PROBLEM TO BE SOLVED: To heat the entire part of a metallic sheet to a desired temp. and to prevent the degradation in the yield of heating up and heating over the entire part of this metallic sheet by the instability in heating up at its ends by adequately adjusting the spacing of power feed rolls at the time of heating the metallic sheet by directly energizing the metallic sheet. SOLUTION: The metallic sheet 1 traveling in an arrow direction is energized from a power source 5 via the upstream side power feed roll 2a of a small diameter and the downstream side power feed roll 3a of a large diameter and is heated to a desired temp. by Joule heat. The traveling of the metallic sheet 1 is stopped and is rolled down by pressing rolls 2b, 3b when the front end of the metallic sheet 1 bites between the downstream side power feed roll 3a and the pressing roll 3b. Next, the power feed roll 2a is moved to the position where this roll lines up with 3a; thereafter, the energization to the metallic sheet between the two power feed rolls 2a and 3a is started and simultaneously the power feed roll 2a and the press roll 2b are traversed reverse from the traveling direction. The rolls are moved under energization to the prescribed position and are then stopped. The traveling of the metallic sheet is then restarted and is continuously heated, by which the metallic sheet is heated to the desired temp. from the front end to the terminal. The failure in heating up to the desired temp. at the ends by the insufficiency of heating is prevented and the entire part of the metallic sheet is heated uniformly to the desired temp.
